The Oakland A’s potential site for a new stadium is now mostly a parking lot, but underneath the asphalt of Howard Terminal lies a buried legacy of industrial use going back a century.

Chronicle reporter Kimberly Veklerov’s review of regulatory documents show soil and groundwater on the site contain hazardous and cancer-causing chemicals that would need to be remedied before a ballpark could be built there.

Team president Dave Kaval says they’ve factored that into the overall plan to build the ballpark — and that the development presents an opportunity to finally clean the land.

But the extent of the work to be done is still unknown — and experts say the complete removal of contaminated dirt is unlikely.

• Grant Way: BART directors unanimously approved a request from Oscar Grant’s family to rename a side street near Fruitvale station in Grant’s honor. Wanda Johnson, Grant’s mother, called the vote a form of “atonement” by the agency, but said the family will continue to press for BART to rename the station.

• New hip, same Bochy: Will this be Bruce Bochy’s final season with the Giants? Not so fast, says Bruce Bochy. The Giants manager says he hears the whispers he’s getting too old to run a team, Scott Ostler writes, but he has no interest in leaving.

• Clean power plans: More than 250,000 San Francisco homes and businesses are about to become customers of San Francisco’s municipal electricity program, CleanPowerSF. While the electricity is procured by the city’s public utilities comission, PG&E is still in charge of distribution, billing and outages. Now commision officials are crunching the numbers to see whether the city could afford to buy PG&E’s infrastructure.

• She can’t do a column on everybody: A week after Heather Knight covered the case of Zander Brandt — who owed San Francisco General Hospital more than $90,000 because of the hospital’s balance billing system — his insurance company informed him he now only owed a $250 co-pay. Now two more people she asked the hospital about have had their bills canceled or put on hold. Instead of responding to cases with media attention, Knight argues, SFGH should cancel all of the astronomical bills while the city studies how to change billing.

• Food myths: Are you worried about getting enough “superfoods”? Don’t be, says one nutritionist who’s frustrated by industry-backed studies that purport to show the superpowers of ingredients like almonds or pomegranate. It’s not that the foods aren’t healthy, she tells Tara Duggan, but that the claims are overstated or omit similar foods that are just as healthy.

Where could you have possibly seen the Beastie Boys for $15? None other than Wolfgang’s, a 600-person venue in San Francisco’s North Beach, on Feb. 2, 1987.

A packet of photo negatives depicting that performance (taken by a future Pulitzer winner) was recently discovered in The Chronicle’s archive. All but one of the images were scanned for the first time this week — and show the rappers in the rare window between being relatively unknown act to punk/rap royalty.
